The core components of the high voltage live display device are sensors and displays. The sensor is responsible for sensing the presence of high voltage electricity and transmitting the signal to the display; the display reflects the live state of high voltage electricity through specific methods (such as lights, digital displays or sound alarms).
2. Detection principle
Electric field or magnetic field perception: When the high voltage line is energized, it will generate an electric field or magnetic field around it. The sensor determines the live state of the high voltage line by sensing the changes in these electric or magnetic fields.
Non-contact measurement: The sensor usually adopts a non-contact measurement method to avoid the safety risks brought by direct contact with high voltage electricity. This measurement method is not only safe, but also ensures the accuracy and stability of the measurement.
3. Technical features
High sensitivity and accuracy: The sensitivity of the indoor high voltage live display device sensor determines whether it can accurately sense weak high voltage electrical signals. In order to improve the performance of the sensor, advanced materials and precision processing technology are usually used. Accuracy is related to the reliability of the detection results, ensuring that the operation and maintenance personnel can obtain accurate information on the live status of the high-voltage line.
Intuition and stability: The display needs to be able to intuitively reflect the live status of the high voltage. Modern high-voltage live display devices mostly use low-power, high-brightness display technologies such as LED to ensure that they can still work normally in harsh environments.
4. Application and coordination
Forced locking function: indoor high voltage live display device sensor High-voltage live display devices are usually implemented with other anti-error devices such as electromagnetic locks and microcomputer five-proof locking devices to implement forced locking. When the high-voltage equipment is energized, the device outputs the locking contact, the control circuit is locked, and it cannot be operated electrically. Only when the high-voltage equipment is without power, the contacts are closed to meet the operating conditions.
Field application: The device is mainly installed in line grounding knives, busbar grounding knives, busbar transformer grounding knives, switch cabinets and other places that need to be locked. It can prevent electrical misoperation and ensure the safe operation of the power system.
In summary, the indoor high voltage live display device sensor can accurately detect the live state of high voltage lines by sensing the changes in the electric or magnetic field around the high voltage lines, using a non-contact measurement method, combining highly sensitive and accurate sensors with intuitive and stable displays. At the same time, it ensures the safe operation of the power system by coordinating with other anti-error devices and meeting the requirements of relevant test items and standards.
